Setting up a docker instance of Elasticsearch Cluster.
In the instructions it says
Make sure Docker Engine is allotted at least 4GiB of memory
I am ssh'ing to the host, not using docker desktop. How can I see the resource allotments from the command line?

I had same problem, with Docker Desktop on Windows 10 while running Linux containers on WSL2.
I found this issue: https://github.com/elastic/elasticsearch-docker/issues/92 and tried to apply similar logic to the solution of there.
I entered the WSL instance's terminal by
wsl -d docker-desktop command.
Later I run sysctl -w vm.max_map_count=262144 command to set 'allotted memory'.
After these steps I could run elasticsearch's docker compose example.
I'd like to go about it by just using one command.
docker stats -all
This will give a output such as following
$ docker stats -all
CONTAINER ID NAME CPU% MEM USAGE/LIMIT MEM% NET I/O BLOCK I/O PIDS
5f8a1e2c08ac my-compose_my-nginx_1 0.00% 2.25MiB/1.934GiB 0.11% 1.65kB/0B 7.35MB/0B 2
To modify the limits : when you're making your docker-compose.yml include the following at the end of your file. (if you'd like to set up a 4 GiB limit)
resources:
limits:
memory: 4048m
reservations:
memory: 4048m
